From The Gulag .... (Solzhenitsyn)
Here is a rewarding and inexhaustible direction for your thoughts: Reconsider all your previous life. Remember everything you did that was bad and shameful and take thought-can't you possibly correct it now?
Yes, you have been imprisoned for nothing. You have nothing to repent of before the state and its laws.
But..... before your own conscience?
I don't have the Gulag for a purgation on earth. Is it a pity or a blessing when considering eternity?
Oremus pro invicem!
